This version includes new AVX2-specific scrypt and SHA-256d routines, which bring an 85%+ speedup to the new Intel Haswell processors. I have tested the new code on a Core i7 4770 (4 cores, 8 threads, 3.4 GHz), and the results seem pretty good: over 95 kh/s for scrypt, and over 50 MH/s for SHA-256d.

Pooler, thanks for fixing the output on stderr. It now flushed one line at a time (instead of the whole buffer every 5 or so minutes), giving nice readable output in my Crypto Miners in Tray front-end.

“Dark times lie ahead of us and there will be a time when we must choose between what is easy and what is right.” “We are only as strong as we are united, as weak as we are divided.”“It is important to fight and fight again, and keep fighting, for only then can evil be kept at bay, though never quite eradicated.”

I am using cbuchner1's cudaminer which is developed on top of cpuminer. I have a show stopper problem with a new version of cudaminer which starts to have stratum support. I get this error message when mining on us.weminltc.com:

[...] stratum_recv_line failed to parse a newline-terminated string

Since it completely stops the miner, instead of skipping the line and keep working, I have to go back to getwork+stratum_proxy

version 2.3.232bit version for sha256d is not working for me (just hangs) but works fine on scrypt.I have no problems with the 64bit version for scrypt or sha256d.

Tested on 32bit win xp and server 2003

I use v2.2.3 if I need to run sha256d on 32bit systems.

Confirmed on Windows XP, though interestingly enough it seems to run with no problem at all in wine.Even more interesting is the fact that if I build it with a different version of gcc it appears to run fine everywhere. I have now uploaded this build, please see if it works for you.

sha256d is working on XP 32bit on new build.no more stratum proxies yay! (Although I did like seeing the difficulty level for each share)Thanks Pooler!

You can use my front-end controller application Crypto Miners in Tray. In addition to lots of automatic start/stop/watch/keep alive options, it has "Run with Windows" checkbox, which will autostart everything once you log in.
